4 – English CHAIN SA W SAFETY EQUIPMENT This section explains the various safety features of the saw, how they work, and basic inspection and maintenance you should carry out to ensure safe operation. (See the ”What is what?” section to find out where these components are on Your saw).
English – 5 SAFETY INSTRUCTIONS 2 The front hand guard is not designed solely to activate the chain brake. Another important safety feature is that it prevents the chain from hitting your left hand if you lose your grip on the front handle.
6 – English 6 The way the chain brake is triggered, either manually or automatically, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes.
English – 7 4 Vibration damping system Your chain saw is equipped with a vibration damping system that is designed to minimise vibrations in the handles and make operation easier. When you use a chain saw vibrations are generated by the uneven contact between the chain and the wood you are cutting.

14 – English 1 Undo the bar nuts that hold the clutch cover and chain brake, using the combination spanner. Then tighten the nuts by hand as tight as you can. 2 Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner.
English – 15 C Checking chain lubrication • Check the chain lubrication each time you refuel. Aim the tip of the saw at a light coloured surface about 20 cm away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.
16 – English H Bar Check regularly: • Whether there are burrs on the edges of the bar. Remove these with a file if necessary. • Whether the groove in the bar has become badly worn. Replace the bar if necessary. • Whether the tip of the bar is uneven or badly worn.

20 – English SAFETY INSTRUCTIONS Two factors decide whether the chain will jam or the log will split. The first is how the log is supported and the second is whether it is in tension. In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom of the log.
English – 21 SAFETY INSTRUCTIONS 2 The log is supported at one end. There is a high risk that it will split. A Start by cutting from below (about 1/3 of the way through). B Finish by cutting from above so that the two cuts meet. 3 The log is supported at both ends.
22 – English SAFETY INSTRUCTIONS FELLING CUT The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut with the bottom edge of the bar. Make the FELLING CUT about 3-5 cm (1.

32 – English MAINTENANCE Adjustment of the oil pump The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The saw is supplied from the factory set to 1 turn open. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.
